Indoor Air Pollution
We spend a large part of our lives indoors at home. Keeping the air which we breathe at home clean is therefore important, particularly for those most sensitive to pollution.
Usually air inside the home is fairly clean, but pollution can build up if ventilation is bad, and there are faulty gas appliances which give off carbon monoxide and nitrogen oxides. If your parents smoke, this will also increase the amount of carbon monoxide indoors. Ask them to open a window or to smoke outside.
Biological pollutants also exist indoors. Dust mites come from bedding and furniture, and some people can be allergic to them. A damp mouldy room will release mould spores into the air, which are also a form of indoor air pollution.
